Note related to batteries, code B1:
(B1) Device with a more powerful charger, which does
not have a battery pack, nor the possibility of
installing them in the same box.
If the battery module is required, it will need to be
ordered as a separate item, which will be connected
to the UPS using the supplied cable.
Before connecting a module or group of batteries to
the unit or another available module,
to check that the voltage value printed on the back of
the device next to the battery connector is appropriate
and that the polarity between the means of connection
corresponds.

optimum protection of any critical load, maintaining the supply
voltage of the loads between the specified parameters without
interruption during failure, deterioration or fluctuation of mains
power, and come in a wide range of models (from 0.7 kVA to 3 kVA),
enabling the end user to select the model that best suits his needs.

The double converter principle eliminates all mains power distur-
bances. A rectifier converts the AC current of the mains into DC
current, thereby maintaining optimum battery charge level and
powering the inverter, which, in turn, generates a suitable AC sine-
wave voltage for continuously powering the loads. In the event of
failure of the UPS's mains power, the batteries supply clean power
to the inverter.
The design and construction of the
has been carried out in accordance with international standards.
This series has therefore been designed to maximise the avail-
ability of critical loads and ensure that your business is protected
against variations in voltage, frequency, electrical noise, interrup-
tions and micro-interruptions, present in power distribution lines.
This is the primary goal of
